This is a shame really, I was looking forward to Facebook & Apple getting this right, imagine if the user is a Ping User, and they're online right now. Seeing a 'Listening to ...........' under their name, and you click on the link, takes you directly to iTunes to preview and download it.
Also if it could dynamically update your favourite music based on your plays too, that would be good integration.
